Collapse form - crashing

@mikhail wrote:

I am trying to get collapsable form implemented. And I am having a crash issue caused by lines 69 and 75. When the dialog tries to get resized.
If I comment those out they “work” as in text shows up and get’s hidden.
But as soon as its uncommented it just brings everything down.

I am using this as an example

Here is what I have right now.
Clearly, there is a syntax issue or something, I just can’t figure out what I should change to get it to work correctly.
Any advice is much appriciated.
